THERAPEUTICAL INSTRUMENT Application led May 31, 1924, Serial No. 716,857, and in'Japan .Tune 15, 1923.

This invention relates to a therapeutical instrument consisting in a pressure-giving tube provided within an outer barrel, the said pressure-giving tube being actuated by a 5 spring, a bristle case containing a large number of bristles of flexible metal planted therein, actuated by av weak spring, the bristles being guided by small holes pierced through a guide plate, and a pressing head or knob rovided at the upper extremityof the outer arrel. The object of this instrumentis to treat disease by applying this instrument to the affected part and giving to that part a special pressure and stimulus, without lgiving pain or causing bleeding.

The accompanylng drawing shows an example of a convenient form embodying thisy invention, in which o Fig. 1 is a perspective view 2 bristle case, which is shown uncut,

Fig. 3 is alsoa vertical section, showing the mode of using myinstrument, and

Fig. 4 is a perspective view of the bristle case,part being opened to show the internal structure. Y

The same reference character refersto the same or corresponding partl throughout all the figures.

To explain my invention in detail with reference to the annexed drawing, to one end of an -outer barrel (A) is screwed a ide tube (B), and between a shoulder on the forwardV end of this guide tube (B),y which projects inward, and a pressing ring (D) fixed to the inner side of the outerbarrel (A), is placed a pressure-giving tube which has a shoulder at its upper end, projecting outward, insuch a way that while 40 the instrument is not used, the shoulder (E) is in'contact with the shoulder (C), the pressure-giving tube being pressed to that position by a spring To the upper end of the louter barrel (A) is screwed a pressing head or knob (H) which is in weight about two-thirds of the whole instrument. Within the barrel (A) is placed a bristle case (I) having its Vupper part enlarged as. at (J). The bristle case (I) is so placed within the outer barrel (A) that its enlarged part lies Fig. 2 is a vertical section, except lthe v ringy (D), the-pressure-giving tube (F) will between the pressing ring (D) and the knob (H), and is pressed against the pressing ring (D) by a spring (K), while its lower part loosely passes through the pressing ring (D), the spring and pressure-giving tube (F). .55 To the bristle case is screwed a seat (L) in which is planted a large number of bristles (M) of fine flexible metallic wire. These bristles are held in their proper position being loosely passed` through small holes', one i60 bristle through one hole, of a guide plate Ywhich vis fixed to one lend of a. rod (N) firmly Vwardly projecting shoulder (E), andthe spring' G) being compressed by the pressing- 2*?0 be pressed against the body. At the same time,the pressing ring (D) being pushed downand freeing the enlarged part of the bristle case, the spring will push down'g' the bristle case and the bristles will give de'- sirable stimulus to the compressed partl of the body. The bristles being of fine, flexible wires 'of metal, and being loosely `passed Y through the small holes, and the spring which 0v presses the bristle case being weak, when they are pressed against the body, they are not strong enough to break through the skin, but will bend, giving only stimulus to the body.

And as the instrument is provided with a,: ,5'

heavy head, it can'be applied to the body vertically with steadinesswhenthe head is pressed with the fingers. Thus the instrument can be applied to the body from several seconds to several minutes without causing` 99 bleeding or giving any pain, except the special pressure and stimulus which is desirable.

Having now fully described this invention what I desire to haveprotected is f l. A therapeutical instrument comprising-19.5 a barrel,a yieldingly mounted bristle carrier carried thereby, and a plurality of relatively long flexible bristles mounted in said carrier.

2. A therapeutical instrument comprising 1.00

a barrel, a relatively long bristle carrier sliding in yielding relation thereto, said carrier having e plurality of long ilexible bristles rigidly secured thereto at its inner end and a guide near its outer end for holding the bristles in spaced relation, the bristles being freelyl movableY longitudinally in said guide so as to be freev to bend at their centers under an excess of pressure.

In testimony whereof I aliix my signature.
